One Indian Army officer and one policeman were killed and three other security personnel seriously wounded in a gunbattle with suspected militants in Jammu and Kashmir state on Sunday, the police said according to DPA. Major Bhanu Pratap Singh and police constable Sanjeev Raina were killed in a clash with militants of the Lashkar-e-Toiba group, defence spokesman SD Goswami said. A special force comprising soldiers and policemen were carrying out search operations in a heavily forested area near Thana Mandi in Rajouri district, about 190 kilometres north of the state's winter capital Jammu, when a group of five to six militants opened fire, he said. He said two soldiers and another policeman were injured. In a separate incident on Sunday, one tourist was killed and six injured when suspected militants lobbed grenades at a tourist vehicle in the resort of Gulmarg, about 65 kilometres west of the state's summer capital Srinagar. Security forces cordoned off the area to track down the militants responsible for the attack. Two of the tourists, including a girl, were in serious condition, the police said.
